n.1. on :EvAN-sroit,

Be' it (known 'that We, ALEXANDER Mnnn andVv DONALD Hf'Svvnnryresidingjat Villa' larln in. the County? O D'l-Pgwdi State. of'Illinoigi; and' at' Evanston, nthe' county O'Cookand' Stat-'enfvillinois, responfor'the Vconvenience 'of 'the user Ain" drawingthertelephone instrument toward him for use and pushing it away when' itis not Wanted.

One 'object of the invention lis to eliminate' unnecessary' ymovement'lin; usingY telephones, especially those Which are movablyinounted onextensible supportsfto' bev 4drawn"towards the `user When in use.

Another object is toi call the operator automatically when suchatelephone isdrawn tovfards the user, independent' of anyInanipulationgothe .ear piece. Another :object is to bringtlretelephone' and ear pieceboth' into operative'juxtaposition Withthe mouthand ear respectively of the `user by a single simple movement of onehand only, leaving the otherhand Yentirely free atall timesto Write downmemorandal or for Manyother purpose.r f

Anotherobj'ect is to leave both handsen` tirely free' while conversingoverI the telephone.

Further objects and advantages of vthe in-l vention will become apparentas the description proceeds,

In the accompanying drawings a'v Figure l is a side elevation, and

Fig. 2 isiA apartial plan view-of an illustrative embodiment of theinvention; and

Fig. 3 is a detail of the clamp for the ear piece Support.

In the embodiment of the invention selected for illustration, We haveshown an ordinary desk telephone comprising a base 10, a standard l2 anda mouth piece 14. The usual hook 16 is provided, adapted to connect anddisconnect the electric circuit' through the instrument. Ordinarily thisis accomplished' the hookf'do'vvn' i with"thewveightfofthe' earpiece, orby yre'- moving the ear piece vto let the hook iiy up' under' thevaction of a suitable spring (not shown) Various tyres' of eXtensiblelinkages" ate' employed'for the'iconvenience ofthe users' of suchtelephones; XVehave illustrated 'a standard '18 supported by anveXtensible' Alink- '.20 in this` 'instance of 'the lazy-tongs variety.V`racket `22 gripsf'standardslS and 12 to` fasten' themtogether'.yAccording to 'the "present 'invent-ion `suitable means are provided forsupporting the ear'piece'-24 at all'times'insuolr` a position thatlwhenV the user istalki'ng into-` mouth piece 14 his ear Will be'conveniently junta-VK posed1to.` the ear' piece 24. Vtehaveillus:trated-'a standard 26 mounted on bracket 22 byV means. of bolt 28 havinga, transverse' l i slotted' hole fto receive the standard: A 'Washer 30is provided; Withlarcuate Anotches at132'to "fit standard. 26 and locknut- -34'z Will force'standardA against Washer 30 andA Washer 'SOagainstf 'bracket '22," to f hold Ythe parts yin juxtaposition lbylfriction. i When freely about-y its oi'vn axis, and standard '26cangslidethrough'A thebolt andalso rotate about itsoWnfaXisf*Receiver24fis-attached mea'ns'oil set' screu7 40;" I n'thi'svvay completeadjt'ist-ment'vo earpiecel 24 tothe precise position required bythe-physicalicharacteristics of the user is provided. Y

Rod 26 is bent at ri. ;ht z tnglesiatthel bottomasat162i and terminatesin lan eye G4 connected by linkfltor the intermediate' pivot 68.o;t;linl.44.v `NVhen the telephone is lpushed backI the ear piecelvvill-swing.l aromi'dvout ofV the fvvay,.and When the parts arepulled out it will swing fonwvafrd r intoA operative positionilt willbeiobvious that the means :fory moving the ear pieces in and out may beomitted if desired.

Suitable means Aassociated With the eX- tensible` support are providedfor automatically permitting hook 16 to rise When the instrument isdrawn toward the user. `With a linkage type of eXtensible support, thismeans may conveniently comprise a single piece of spring Wire extendingthrough the pivotal connection at 42 belCO tween standard 18 and link 44of the linkage. One end of the wire extends upward to pass through oneof the other pivots 46 of link 44, whereby the wire tends to rotateabout point 42 as a pivot when the linkage is expanded. From pivot 42the other end of the wire extends in any suitable or convenient way toterminate in a hook '48 overlying the narrow portion of hook 16. As thishook moves about point 42 of the center, its outer end 50 shouldpreferably be curved substantially in the arc of a circle around point42. In the embodiment shown, slight additional resilience is provided inthe wire by extending it forward as at 52 then laterally as at 54, thencoiling it around itself as at 56 and finally forming a small coil 58 toembrace part 54 and constitute a pivot between reach 52 and theintermediate reach 60 extending to hook 48. It will be obvious that asfar as the broader aspects of the invention are concerned, theresilience required may be provided by a helical coil located eithersideV of pivot 42, or by employing wire of proper diameter, suitableaction can be obtained without any coil at all. Any element fastened toor moving with link 44 could be an effective substitute for the wire. n

Without 'further elaboration, the foregoing will so fully explain thegist of the invention, that others may, by applying current knowledge,readily adapt the same for use under various conditions of service. Itwill, for instance, be obvious that by omitting the arm 62, and leavinglock nut 34 a little loose, the ear piece could be swung around thehorizontal axis of bolt 28 instead of around the vertical axis ofstandard 26. This and many other modifications and alterations may bemade without eliminating certain features which may properly be said toconstitute the. essential items of novelty involved, which items areintended to be defined and secured to us by the following claims. i

We claimz- Y 1. In combination, a telephone instrument comprising' atransmitter and a receiver, an extensible support for carrying theinstrument substantially horizontally to and from the user, circuitcontrol means, and means for automatically operating said control meansto adjust the circuits for talking lfor holding said receiver spacedfromsaid transmitter.

3. In combination, a telephone instrument comprisingY a transmitter anda'receiver, an extensible supportfor carrying the instrumentsubstantially horizontally to and from the user, circuit control means,means for automatically operating said control means to adjust thecircuits for talking upon pulling the instrument toward the user, and toadjust the circuits for ringing upon pushing the instrument away fromthe user, said instrument including a support for holding said receiverspaced from said transmit-ter, said support vbeing movable, andconnections for retracting said support when the entire instrument ispushed away from the user.l

4. The combination with a lazy tongs support and a telephone instrumentmounted on the extensible end thereof, said instrument including areceiver and a transmitter, of circuit controlling means" movable intotwo positions, i. e. a first talking position and a second ringingposition, and a connection for automatically shifting said circuitcontrolling' means from the second to the first position upon extensionof said support, and vice versa. y

5. In combination, a telephone desk stand including a transmitter, areceiver and a switch hook, a horizontally extensible support for saiddesk stand, and means controlled by the movement of said extensiblesupport for raising and lowering the switch hook independently of saidreceiver.

In witness whereof, we hereunto subscribe our names this 13th day ofAugust, 1923.
